Dear BS experts:
I was trying to compute sources with mean entrophy as I usually do (I have already computed head model with duneuro FEM, I set the noise covariance), but this time I got an error:

However, I was able to compute sources without any issue using the Current Density Map option for Minimum Norm.
Thanks in advances!
UPDATE: I managed to solve this: I deleted the previous computed noise covariance and I recomputed the sources setting the baseline within the cMem option
